We construct a large new class of de Sitter (and anti de Sitter) vacua ofcritical string theory from flux compactifications on products of Riemannsurfaces. In the construction, the leading effects stabilizing the moduli areperturbative. We show that these effects self-consistently dominate overstandard estimates for further $\alpha^\prime$ and quantum corrections, viatuning available from large flux and brane quantum numbers.Comment: 26 pages, harvmac big. v2: Correction generalizing specific ingredients required for tunable negative term; conclusions and structure of potential unchange
